Definitions

  • the invention relates to a straddle carrier provided with wheels for moving freight containers across a yard, which wheels comprise at least two steerable wheels, whilst the straddle carrier further comprises at least one portal frame as well as at least one frame which is movable with respect to said portal frame for picking up, lifting and/or carrying a freight container, using gripping means.

  • Such a straddle carrier is known from US-D-526,932S.
  • the straddle carrier known from US-D-526.932S comprises a portal frame comprising two parallel, substantially vertically extending portal structure members, which are provided with wheels at their lower end and which are interconnected by means of at least one bridge member at their upper end.
  • Mounted to the bridge member of the known straddle carrier is a frame that can be moved up and down for picking up, lifting and/or carrying a freight container.

  • the object of the present invention is to provide an improved straddle carrier by means of which a larger number of freight containers can be moved a certain distance per unit time.
  • the movable frame is arranged for picking up, lifting and/or carrying at least two parallel, side-by-side freight containers at a time with the longitudinal sides of the two freight containers facing each other.

Productivity is significantly enhanced by using the straddle carrier according to the present invention.
  • Another advantage of the straddle carrier according to the present invention is the fact that more freight containers can be stored on the same yard area than is for example possible with the straddle carrier shown in US-D-526.932S.
  • the fact is that space is needed between all the parallel, facing longitudinal sides of the freight containers when using the known straddle carrier, so that the wheels of the straddle carrier can move between the freight containers for picking up each freight container in the yard and moving it.

  • the straddle carrier according to the present invention has very advantageous dimensions.
  • the portal frame is relatively wide, because at least two parallel, side-by-side freight containers can be picked up, lifted and/or carried by means of the movable frame between substantially vertically extending structural members of the portal frame.

  • the construction of the straddle carrier according to the present invention may be substantially the same as that of the straddle carrier that is known from US-D-526.932S.
  • JP-09-151076 discloses a transfer crane which comprises wheels for moving only a longitudinal direction over a yard for picking up, lifting and/or carrying freight containers by means of trolleys. These trolleys can move in a transversal direction to said longitudinal direction. A crane as a whole cannot travel at relatively high speeds across a storage yard in more than one direction.
